TECHNICAL FIELD

The present technology is directed to semiconductor packages with indications of die-specific information. More particularly, some embodiments of the present technology relate to a semiconductor package with machine-readable codes thereon for indicating information (e.g., operations parameters) regarding a semiconductor die in the semiconductor package.

BACKGROUND

Packaged semiconductor dies, including memory chips, microprocessor chips, logic chips and imager chips, typically include a semiconductor die mounted on a substrate and encased in a plastic protective covering. Individual semiconductor die can include functional features, such as memory cells, processor circuits, imager devices and other circuitry, as well as bond pads electrically connected to the functional features. To properly operate the semiconductor die, certain die-specific parameters for operating the semiconductor die, such as current, voltage, resistance reference values, etc., must be optimized at die level to account for process variations, for example. Such die-specific parameters are traditionally stored in special non-volatile elements, such as fuses or anti-fuses, that are realized in the die itself. This can be expensive and unreliable.

DETAILED DESCRIPTION

Specific details of several embodiments of stacked semiconductor die packages and methods of manufacturing such die packages are described below. The term “semiconductor device” generally refers to a solid-state device that includes one or more semiconductor materials. A semiconductor device can include, for example, a semiconductor substrate, wafer, or die that is singulated from a wafer or substrate. Throughout the disclosure, semiconductor dies are generally described in the context of semiconductor devices but are not limited thereto.

The term “semiconductor device package” can refer to an arrangement with one or more semiconductor devices incorporated into a common package. A semiconductor package can include a housing or casing that partially or completely encapsulates at least one semiconductor device. A semiconductor device package can also include an interposer substrate that carries one or more semiconductor devices and is attached to or otherwise incorporated into the casing. The term “semiconductor device package assembly” can refer to an assembly that includes multiple stacked semiconductor device packages. As used herein, the terms “vertical,” “lateral,” “upper,” and “lower” can refer to relative directions or positions of features in the semiconductor device or package in view of the orientation shown in the Figures. These terms, however, should be construed broadly to include semiconductor devices having other orientations, such as inverted or inclined orientations.

FIG. 1 is a schematic diagram of a system 100 for delivering information regarding a semiconductor die in a semiconductor device package in accordance with an embodiment of the present technology. The system 100 includes a semiconductor device package 101, a semiconductor die 104 in the semiconductor device package 101, an indication 103 on the semiconductor device package 101, an indication reader 105, a controller 107, and a data storage 109. In some embodiments, the semiconductor device package 101 can be a portion (e.g., the upmost portion) of a semiconductor device package assembly, which can include multiple stacked semiconductor device packages.

As shown in FIG. 1 , the semiconductor device package 101 has a designated area 102 for displaying the indication 103. In some embodiments, the designated area 102 is located at a top surface of the semiconductor device package 101. In some embodiments, the designated area 102 is located at a bottom surface of the semiconductor device package 101. In some embodiments, the designated area 102 is located at a side surface of the semiconductor device package 101. In some embodiments, the semiconductor device package 101 can have more than one designated area 102 at different locations (e.g., two different locations at the top surface; a location at the side surface and another location at the bottom surface, etc.).

The indication 103 is configured to present or deliver information associated with the semiconductor die 104 in the semiconductor device package 101. The information associated with the semiconductor die 104 can include, for example, suitable current, voltage, voltage adjustments, delays, redundancy information, firmware instructions, power-on/off instructions, etc., for operating the semiconductor die 104. In some embodiments, the information associated with the semiconductor die 104 can include a testing result for the specific semiconductor die 104 (e.g., the testing result can indicate how the semiconductor die 104 performs under certain conditions or environments). In some embodiments, the information associated with the semiconductor die 104 can be used to achieve optimal functionality of the semiconductor die. For example, the information can include a voltage range V₁-V₂ to achieve proper performance of the semiconductor die 104. For example, the information can include trimming parameters for voltages, current generators, and/or regulators. For example, the information can include addresses for redundancy, such as addresses of failing memory locations that can be replaced by functional memory locations. As another example, the information can include a set of instructions that needs to be loaded to a processor to power up and control the semiconductor die 104.

In some embodiments, the indication 103 can include a set of machine-readable codes. In some embodiments, the indication 103 can include a pattern, a one-dimensional barcode, a two-dimensional barcode (e.g., a matrix barcode such as a Quick Response (QR) code), and other suitable codes. In some embodiments, the indication 103 can be positioned or formed on the semiconductor device package 101 by a printing process. In some embodiments, the indication 103 can be positioned or formed on the semiconductor device package 101 by one or more processes involving stamping, etching, engraving, lasering, thermal molding, adhesives, etc.

The indication reader 105 is configured to read the machine-readable codes of the indication 103. In some embodiments, the indication reader 105 can be an optical scanner. In some embodiments, the indication-reader 105 can be a barcode reader. In some embodiments, the indication-reader 105 can be a laser scanner. The indication reader 105 is coupled to the controller 107 and controlled thereby. For example, the controller 107 can instruct the indication reader 105 to initiate a reading process to read and analyze the machine-readable codes in the indication 103 and accordingly obtains the information associated with the semiconductor die 104. The information associated with the semiconductor die 104 can then be sent to the data storage 109 for future use.

In some embodiments, the data storage 109 can be a storage device or a disk drive coupled to the indication reader 105. In some embodiments, the data storage 109 can be a database communicably coupled to the indication reader 105 (e.g., via a wired or wireless network such as the Internet or an intranet).

In some embodiments, at least a portion of the information associated with the semiconductor die 104 can be stored in a non-volatile component (e.g., a fuse, a non-volatile memory, etc.) of the semiconductor device package 101. In such embodiments, the information stored in the non-volatile component can be directly accessed by the operator of the semiconductor die 104, without using the indication reader 105. In some embodiments correctness of the information stored in non-volatile components of the semiconductor device package 101 (for example a fuse or a non-volatile memory in the semiconductor die) can be verified by comparison with the indication 103 presented on the semiconductor device package 101 and re-stored if necessary. In other embodiments, however, the semiconductor device package 101 does not have a non-volatile component (e.g., a fuse, a non-volatile memory, etc.) and accordingly the information associated with the semiconductor die 104 is stored by the indication 103.

In some embodiments, the information associated with the semiconductor die 104 can be encrypted for security purposes. In some embodiments, to decode the encrypted information associated with the semiconductor die 104, a key (e.g., a software key) or a passcode may be required. By this arrangement, the present technology provides a secured way to deliver die-specific information such that only authorized operators can access the encrypted information associated with the semiconductor die 104.

In some embodiments, the semiconductor die 104 can be tested for functionality, for example, during an Electrical Wafer Sorting (EWS) test. During the test, a set of optimal operation/working parameters can be determined, such as trimming parameters for voltage/current generators and regulators, addresses for memory cell redundancy, etc. The set of optimal operation/working parameters can be stored in the data storage 109 and/or controlled by the controller 107. In some embodiments, a writing apparatus 106 can be configured to form the indication 103 in the designated area 102 of the semiconductor device package 101, after the semiconductor device package 101 has been packed. For example, the indication 103 can include one or more one-dimensional and/or two-dimensional codes. In other words, the die-specific information associated with the semiconductor die 104 can be encoded and written on its package for future use, as described above.

In some embodiments, the information associated with the semiconductor die 104 can include customized information requested by a user. For example, the user can request a manufacturer of the semiconductor device package 101 to add information in the indication 103. Such information can include, for example, internal batch/reference numbers used by the user, versions of the firmware in the semiconductor die, technical notes regarding how to operate the semiconductor device package 101 created by the user, etc. By this arrangement, the present technology enables a user to add inherent, customized information in the semiconductor device package 101.

FIGS. 2A-2H are schematic views illustrating a semiconductor device package 201 in accordance with embodiments of the present technology. As shown in FIGS. 2A-2H, the semiconductor device package 201 includes an indication 203 (individually identified as indications 203 a-h in various embodiments described in FIGS. 2A-2H, respectively) thereon and multiple connectors 204 (e.g., conductive pins, legs, etc.) configured to couple to an external device.

FIGS. 2A-2D are top views of the semiconductor device package 201. In FIG. 2A, the indication 203 a includes a square-shaped, two-dimensional code at the top surface of the semiconductor device package 201. In FIG. 2B, compared to FIG. 2A, the indication 203 b is also a square-shaped, two-dimensional code with a size smaller than the size of the indication 203 a. In FIG. 2C, the indication 203 c includes a rectangular-shaped, two-dimensional code at the top surface of the semiconductor device package 201. In FIG. 2D, the indication 203 d includes a one-dimensional code at the top surface of the semiconductor device package 201. In some embodiments, the indications 203 a-d can be located at other locations (e.g., at the center) of the top surface of the semiconductor device package 201.

FIGS. 2E-2H are side views of the semiconductor device package 201. The indication 203 e in FIG. 2E is a rectangular-shaped, two-dimensional code at a long, side surface (LSS) of the semiconductor device package 201. In FIG. 2F, the indication 203 f can be a one-dimensional barcode at the LSS of the semiconductor device package 201. The indication 203 g in FIG. 2G is a rectangular-shaped, two-dimensional code at a short, side surface (SSS) of the semiconductor device package 201. In FIG. 2H, the indication 203 h is a one-dimensional barcode at the SSS of the semiconductor device package 201.

Embodiments discussed in FIGS. 2A-2H include indications at respective designated areas of a surface of the semiconductor device package 201. In some embodiments, the designated area can be positioned/aligned with respect to other marks (e.g., a manufacturer logo) and/or structural elements (e.g., package corner, conductive leg, etc.) that are conveniently identifiable so that the indications can be formed without using a reference sign (e.g., an alignment mark). This arrangement enables efficient uses of the designated areas (e.g., which can be used for storing more information).

FIGS. 3A-3D are schematic views illustrating methods of delivering information regarding a semiconductor die in a semiconductor device package in accordance with embodiments of the present technology. FIG. 3A illustrates a reel system 30 configured to carry multiple semiconductor device packages and provide the corresponding indications for each semiconductor device package. The reel system 30 includes a tape 31 having multiple recesses 32 a-b configured to carry a semiconductor device package and/or an indication with the die-specific information. The reel system 30 also includes a top cover 33 and a bottom cover 35 configured to protect the tape 31 and the multiple semiconductor device packages carried by the tape 31.

The embodiment shown in FIGS. 3A and 3B has a first semiconductor device package 300 a in recess 32 a and a second semiconductor device package 300 b in recess 32 b. The tape 31 also includes areas 36 a-b and indications 37 a-b at the areas 36 a-b, respectively. The indication 37 a associated with the first semiconductor device package 300 a can be at area 36 a. Similarly, the indication 37 b associated with the second semiconductor device package 300 b can be at area 36 b. Areas 36 a-b can be recesses as shown in FIGS. 3A and 3B, or they can be an embossment or a flat surface.

Referring to FIG. 3B, the tape 31 can be moved and processed in a feeding direction F such that the indication 37 b with the die-specific information for the second semiconductor device package 300 b is read before the second semiconductor device package 300 b is accessed or processed, and then the indication 37 a with the die-specific information for the first semiconductor device package 300 a is read before the first semiconductor device package 300 a is accessed or processed. Accordingly, when accessing and/or processing the semiconductor device packages 300 a-b, an operator (or a corresponding system) can have specific information about how to properly handle and/or operate the semiconductor device packages 300 a-b. For example, the die-specific information for each of the semiconductor dice in the semiconductor device packages 300 a-b can be stored in configuration elements (e.g., fuses, anti-fuses, etc.) in corresponding semiconductor die or stored in a system memory, which can later be used to power on the corresponding semiconductor die.

In some embodiments, the die-specific information can be read by an indication reader, under control of a controller, and corresponding data can be stored in a data storage. The indication reader, the controller and the data storage can be the indication reader 105, the controller 107, and the data storage 109 depicted in FIG. 1 . In some embodiments, the data storage can be a memory in the semiconductor die (e.g., non-volatile memory cells, fuses, etc.). In some embodiments, the data storage is external to the semiconductor die and the stored data can be accessed and uploaded (e.g., in configuration latches of the semiconductor die) to power on the semiconductor die.

FIGS. 3C and 3D show embodiments in which the indications 37 a-b are printed on the tape 31. In the embodiment illustrated in FIG. 3C, the indications 37 a-b can be printed in front of and adjacent to the recesses 32 a-b, respectively. In the embodiment shown in FIG. 3D, the indications 37 a-b are printed at the side of and adjacent to the recesses 32 a-b, respectively.

FIGS. 4A and 4B show semiconductor device packages in accordance with embodiments of the present technology. In FIG. 4A, a memory device 400 can have a sticker 401 with a barcode 404 and a QR code 406 thereon. The barcode 404 is located in a first designated area 408, and the QR code 406 is located at a second designated area 410. The first designated area 408 and the second designated area 410 can be on the same surface of the memory device 400. In other embodiments, however, the first designated area 408 and the second designated area 410 can be on different surfaces (e.g., two surfaces opposite, or adjacent, to each other). Both the barcode 404 and the QR code 406 are used to carry information associated with the memory device 400 (e.g., parameters for operations). Although embodiments discussed in FIGS. 4A and 4B have two sets of codes 404, 406, in other embodiments, however, there can be other number(s) of code(s), such as one, three or more, etc.

In some embodiments, the barcode 404 and the QR code 406 can be used to carry generally the same information regarding the memory device 400. In such embodiments, an operator of the memory device 400 can retrieve the information regarding the memory device 400 from either the barcode 404 or the QR code 406. For example, the operator can read the barcode 404 by a barcode reader. As another example, the operator can read the QR code 406 by a QR-code reader. In some embodiments, the operator can read both the barcode 404 or the QR code 406 by an optical reader. In such embodiments, the information read from the barcode 404 can be compared to the information read from the QR code 406 such that the information regarding the memory device 400 can be verified.

In some embodiments, the barcode 404 can be used to carry a first portion of information for operating the memory device 400, and the QR code 406 can be used to carry a second portion of the information for operating the memory device 400. This provides flexibility for operating or processing the memory device 400 in different stages. For example, the barcode 404 can store a first set of information to power up the memory device 400 in a first stage (e.g., an initiating stage). The QR code 406 can store a second set of information to operate the memory device 400 in a second stage (e.g., an operating stage). In these embodiments, an operator can use proper scanners to read the barcode 404 in the first stage and the read the QR code in the second stage.

In some embodiments, one of the barcode 404 and the QR code 406 can include authentication information (e.g., a product identification, a customer identification, a manufacturing batch/date, etc.), whereas the other one can include information for operating the memory device 400. In some embodiments, an operator needs to receive the authentication information and then the operator can access the information regarding the memory device 400. For example, the authentication information includes a key for decoding the information regarding the memory device 400. By this arrangement, the present technology provides a secured method for delivering operational information to an operator or a customer.

FIG. 4B shows a stacked integrated circuit (IC) device 407 with a QR code 409 and a barcode 411. The barcode 411 is at a first designated area 412, and the QR code 409 is at a second designated area 414. The first designated area 412 is on a side surface of the stacked IC device 407, and the second designated area 414 is on a top surface of the stacked IC device 407. Similar to the barcode 404 and the QR code 406 discussed above, the QR code 409 and the barcode 411 can include generally the same or different information associated with the stacked IC device 407.

FIG. 4C is an image showing an indication 413 having a pattern of dots in accordance with an embodiment of the present technology. The location of each dot can mean bit information “1” and a space (i.e., without a dot, or an “empty” dot) can mean bit information “0.” By having multiple dots and spaces in the pattern 413, the pattern 413 can be used to provide the die-specific information associated with a semiconductor device package as discussed above. In some embodiments, shapes other than dots (e.g., squares, triangles, segments, etc.) can be used. In some embodiments, the relative positions or relationships of the dots (or other shapes) can be used to encode the information in a pattern.

FIG. 4D shows a memory device 420 in accordance with an embodiment of the present technology. The memory device 420 include nine memory module packages 422 (indicated as 422 a-i in FIG. 4D). Each the memory module packages 422 has a QR code 424 thereon (indicated as 424 a-i in FIG. 4D). The individual QR codes 424 are configured to deliver die-specific parameters for each semiconductor die in the individual memory module packages 422. These QR codes 424 can be optically read and then stored in a storage device (e.g., a non-volatile component 426 of the memory device 420). The storage device can store additional information, for example, information useful for operating the memory device 420. During a power-on process of the memory device 420, the die-specific information can be used to activate/operate each die in respective memory module package 422 and the memory device 420.

FIG. 5 is a block diagram illustrating a system that incorporates a semiconductor assembly in accordance with embodiments of the present technology. Any one of the semiconductor devices described above with reference to FIGS. 1-4D can be incorporated into any of a myriad of larger and/or more complex systems, a representative example of which is a system 500 shown schematically in FIG. 5 . The system 500 can include a processor 501, a memory 503 (e.g., SRAM, DRAM, flash, and/or other memory devices), input/output devices 505, and/or other subsystems or components 507. The semiconductor assemblies, devices, and device packages described above with reference to FIGS. 1-4D can be included in any of the elements shown in FIG. 5 . In some embodiments, the system 500 can include a non-volatile memory for storing die-specific information for at least some of the components in the system 500. For example, configuration parameters (e.g., voltage, current, delay and/or resistance trimming parameters, redundancy addresses, etc.) can be stored in the non-volatile memory and uploaded to corresponding components at a power-on process of the system 500. The resulting system 500 can be configured to perform any of a wide variety of suitable computing, processing, storage, sensing, imaging, and/or other functions. Accordingly, representative examples of the system 500 include, without limitation, computers and/or other data processors, such as desktop computers, laptop computers, Internet appliances, hand-held devices (e.g., palm-top computers, wearable computers, cellular or mobile phones, personal digital assistants, music players, etc.), tablets, multi-processor systems, processor-based or programmable consumer electronics, network computers, and minicomputers. Additional representative examples of the system 500 include lights, cameras, vehicles, etc. With regard to these and other examples, the system 500 can be housed in a single unit or distributed over multiple interconnected units, e.g., through a communication network. The components of the system 500 can accordingly include local and/or remote memory storage devices and any of a wide variety of suitable computer-readable media.
